ATTACHMENT-HOLDERFOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 355,458, dated January25, 1887.

Application filed April 17, 1686.

To all whom it may concern:

Be itknown that I, FREDERICK EGGE, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inSecuring Attachments to Sewing-Machines; and I do hereby declare thefollowing to be afull, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain novel and useful improvements inbutton-hole'sewing attachments for sewing-machines, but has specialreference to the manner of securing the attachment to the sewing machinein the proper position for operation, and has for its object to do awayentirely with the ordinary screw-fastening devices and to utilize theconstruction itself of the the sewing-machine to accomplish the resultaimed at; and with these ends in view my invention consists in certaindetails of construction and combination of elements, hereinafter fullyset forth, and then specifically designated by the claim.

In order that those skilled in the art to which my invention appertainsmay more fully understand the same, I will proceed to describe it indetail, referring by letter to the accompanying drawings, forming a partof this specification, in which- Figure 1 is a bottom perspective of thebedplate of a button-hole-sewing attachment provided with my improvedconstruction; Fig. 2, a plan view of the forward end of a sewingmachinebed, the raceway-slides being partially withdrawn; Fig. 3, a bottom viewof the same with the attachment secured thereto aftravel underneath saidbar.

opening or'openings through which access is had to the shuttle or hook,as the case may be. Furthermore, it makes 'no difference in theapplication of my improvement whether a shuttle or a hook is used, orwhether there are one or two slides.

The bed-plate of the attachment is denoted by E,and the needle-holethereof by F. G is a step secured to or formed with the bed of theattachment, and to this step is secured a cross-bar, H, the extremitiesof which are slightly curved upward, for the purpose presentlyexplained. The length of this step is preferably equal to'the shortestdistance between the throat-plate and the rear wall of the raceway.

In adapting my improvement to a sewingmachine the raceway-slidesarepartiallywithdrawn, as shown in Fig. 2, and the bed of the attachmentis simply placed on the bed-plate of the sewing-machine in such mannerthat the two needle-holes D F will coincide. 'The slides are now pushedinward, and during their travel will strike against the under faces ofthe curved ends of the cross-bar H, and thereby be readily guided intheir further This bar has a slight spring action, which facilitates themovement of the slides and at the same time causes said bar to have astrong frictional bearing on the slides, so that the latter cannotbecome displaced by the vibration or motion of the various parts of theattachment or the sewing-machine. sure the firmness of the attachment,the step G may be made of such length as to have an abutment with therear wall of the raceway and the inner edge of the throat-plate; also,pins I may project from the forward lower face of the bed-plate of theattachment in such manner that when the latter is in proper0perativeposition on the sewing-machine said pins'will lie snuglyagainst the inneredge of the throat-plate, as shown in Fig. 3. However,both the step and pins are merely auxiliary, since the slides and thebar H by actual experiment have proved amply sufficient to secure theattachment.

I have shown my improvement in connec- In order to still further -in-.

tion with the bed-plate of a button-hole-sewing attachment; but it isequally applicable in securing all other attachments that are capable ofbeing fastened in operative position directly to the bed-plate of thesewing-machine. In sewing-machines in which a hook is used instead of ashuttle there is usually a single slide, and in this instance the barneed extend but in one direction, as the single slide is capable ofsecuring the attachment.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the bed-plate of a sewing machine provided withshuttle race slides, of a sewing-machine attachment having upon theunderside ofits bed-plate a two-way projecting spring cross-bar, the arms ofwhich extend transversely upon each side of the center of saidattachment-plate, whereby the slides in closed position may enterbetween the said spring-bar and the attachment-plate, thereby securingthe attachment to the sewing-machine, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK EGGE. Witnesses:
